Blencathra - Hallsfell Top

Blencathra — Hallsfell Top

Blencathra, also known as Saddleback, rises to 867.8 metres, conventionally rounded to 868 metres, in the Lake District's Northern Fells. Hallsfell Top is its highest summit. Threlkeld and Scales lie below its southern slopes.

Choosing a route

The mountain offers several very different approaches. Sharp Edge and Hall's Fell Ridge are both exposed Grade 1 scrambles. Sharp Edge is the more technical of the two, but Hall's Fell is still serious terrain, especially in descent. They require scrambling ability, confidence with heights and suitable conditions; a lower bypass does not remove every exposed move. Cumbria Tourism

A defined circuit from Threlkeld climbs Hall's Fell and returns over Gategill Fell Top and Knowe Crags, descending Blease Fell. This is approximately 8.5 km. The walking-time calculator on its source page is a minimum, not a realistic promise for a group scrambling and taking breaks. WalkLakes route

Another defined circuit starts at the A66 footpath west of Scales, reaches Scales Tarn, climbs Sharp Edge and Foule Crag, then descends Hall's Fell and returns along the lower fellside. TGO describes this as approximately 7.6 km and 4.5 hours; allow longer for conditions, breaks and slower scrambling. Its return includes an awkward crossing at Scaley Beck. TGO route

Blease Fell and Scales Fell provide walking approaches that avoid these two scrambling ridges. They remain steep mountain walks. Doddick Fell, Gategill Fell and the northern approach provide further options; choose a complete mapped itinerary with a suitable descent. Northern routes may include boggy Mungrisdale Common and the loose Blue Screes path. Do not treat an ascent-only distance as a round-trip distance. Route overview

Summit and landscape

The highest point is a rock about a metre north of the low circular trig station; ground a little farther north is about as high. The marker is not a conventional tall trig pillar. Clear conditions offer views towards Skiddaw, the northern fells, Keswick and Derwentwater. Summit information

Nearby tops include Knowe Crags, also called Blease Fell (804.5 m), and Gategill Fell Top (852.2 m). Skiddaw (930.4 m) lies farther west and is a separate mountain outing. Heights and summit details are checked against the Database of British and Irish Hills.

Geology and name

Blencathra consists of Skiddaw Group sedimentary rocks, including mudstone and siltstone, locally altered by the heat of igneous intrusions. These hardened rocks help explain its rugged relief. Later glacial erosion shaped the landscape. The mountain is not principally Borrowdale andesite and lava flows. British Geological Survey

The name is Cumbric in origin. A common interpretation relates it to a summit and a chair or seat, but the second element is disputed. The alternative name Saddleback describes the mountain's profile; Wainwright helped popularise Blencathra. Name study

Safety

Polished rock, exposure and serious fall consequences are central hazards on Sharp Edge and Hall's Fell. Wet rock, gusty winds, snow and ice substantially increase the difficulty. Keswick Mountain Rescue warns that Sharp Edge's lower path still reaches the dangerous gap and does not bypass the whole difficulty. Winter conditions can require winter mountaineering skills and equipment. Keswick Mountain Rescue, 2026 report, pages 14–15

Check a mountain forecast, allow enough daylight, carry independent navigation and appropriate clothing and emergency supplies, and choose terrain suitable for the whole party. Even routes avoiding the scrambling ridges need fitness, navigation and care on steep ground.

Access and facilities

Choose parking to suit the route: Threlkeld for western and southern approaches, or permitted parking near Scales for eastern approaches. Spaces are limited; follow signs, avoid obstructing access and do not assume private Field Centre or pub parking is available to walkers.

Stagecoach X4/X5 services connect Keswick and Penrith through Threlkeld. Check current timetables, the exact stop for Scales approaches and the last return. Stagecoach

Threlkeld has pubs and a coffee shop, with public toilet access at the Village Hall and Coffee Shop subject to opening. The White Horse Inn at Scales offers refreshments; Keswick has a wider range of services. Check opening before relying on any facility. National Park facilities information, White Horse Inn
